Passat B2 '87 and Golf III engine differences

[Pedja_Bg]

Hello all,

I have VW Passat B2 1.6 TD, engine is from Golf II. That engine is broken now and I need new one. I now have good opportunity to buy engine from Golf III, witch is 1.9 TD, and with that engine i get everything with it. (pumps, connectors...)

Do I need to make some changes on my passat B2 or not? Some people says that engine from golf III can't put in my b2, and some peoples says that I can !!??

Now I am confused and I dont know what to do, please tell me what are the changes that a need to make.

Thanks everyone.
